No, `alloca' allocates in much smaller increments, like words or dwords.  
But I don't recommend using it for allocations larger than, say 5KB.  
That is because your function might be called in a deeply nested program, 
when some (most) of the stack is already used up.  Think about `alloca' 
as a way to declare a variable-size local array: usually, when the array 
size gets large, you'd prefer using `malloc' or declare it as a static.  
The same logic applies to `alloca' IMHO.
